A) \[5:3\]
B) \[2:3\]
C) \[3:2\]
D) \[3:5\]
Correct Answer: D
Solution :
[d] Let the ratio be \[\lambda :1\] Dividing point \[P\equiv \left( \frac{-3\lambda +1}{\lambda +1},\frac{4\lambda +2}{\lambda +1},\frac{-5\lambda +1}{\lambda +1} \right)\] Since, this point lies in xy plane. \[\therefore \] z-coordinate will be zero. i.e. \[\frac{-5\lambda +3}{\lambda +1}=\frac{0}{1}\] \[\therefore -5A+3=0\] \[\therefore \lambda =\frac{3}{5}\] Hence, option [d] is correct.You need to login to perform this action.
